Vomerine teeth in two small oblique groups between the choane, 
frequently missing. Head much elongate; snout long, rounded, 
with angular canthus rostralis and deeply concave loreal region ; 
interorbital space narrower than the upper eyelid; tympanum 
distinct, about one third the width of the eye. Fingers slender, 
first shorter than second, with very large disks; toes very broadly 
webbed, with moderate disks; subarticular tubercles rather small, 
The hind limb being carried forwards along the body, the tibio- 
tarsal articulation reaches beyond the tip of the snout. Upper 
surfaces more or less distinctly granular; lower surfaces smooth. 
Above brown, black-spotted, or dark ashy brown, uniform or with 
rounded whitish spots. Male with two internal vocal sacs.

Vomerine teeth in two small oval groups on a level with the 
hinder edge of the choane. Head moderate; snout subacuminate, 
with distinct canthus rostralis; interorbital space as broad as 
the upper eyelid; tympanum two thirds the width of the eye. 
Fingers slender, first extending a little beyond second ; toes moderate,

tubercles well developed; a small oval inner metatarsal tubercle, 
and a small rounded one at the base of the fourth toe. The hind
